The AVAL Science Foundation has been attempting to cause a Second Great Collapse by installing artificial keystones throughout the city! At this rate, everyone in Tokyo will be transformed into monsters, and the city will become a hellscape!
In order to stop their plot, Chihiro and his friends head to the Infinity Theater where Kark Kaburagi is performing a concert. As the reaper's deadly melody rings throughout the theater, total war breaks out between Chihiro's friends and the AVAL Science Foundation.
Will they be able to stop the Second Great Collapse?!
When this Big Dipper is completed, 
the Second Great Collapse will occur.
عندما يكتمل الدبّ الأكبر، يحدث الانهيار
العظيم الثاني
Wenn der Große Wagen fertig ist,
geschieht der Zweite Zusammenbruch.
Cuando se complete esta Osa Mayor,
habrá un Segundo Gran Colapso.
Cuando se complete esta Osa Mayor,
habrá un Segundo Gran Colapso.
Se la costellazione
dell'Orsa Maggiore sarà completata,
Quando o Grande Mergulhador estiver pronto,
o Segundo Grande Colapso ocorrerá.
Когда будет завершена Большая Медведица,
начнётся второе Большое забытьё.
